Probably better done in a 3D application such as Blender.
However, always a way(-ish), so a brief outline. 2D representation depends on light and shading to give an illusion of depth. My advice, trawl for images of the sort of shape you need, to get some ideas.
Gimp can easily make a sphere with lettering if you put it in. Filters -> Map -> Map Object. (edit: an alternative which makes a plain, but nicely shaded sphere is the g'mic plugin http://www.gmic.eu in the render section)

Now you need to make a selection to represent a segment. The best way is a path, but you could draw by hand using a quick mask. Make the path then path to selection.

Next you have to fill that selection with shading. I used a linear gradient (HSV) Just try different starting/ending/ length until you get a result. you could also do this by hand using a fuzzy brush and various colours if you are feeling artistic.

A bit of manual erasing because you need to imagine where the bottom 'pole' is and the line the surface takes to meet that pole. Not quite correct, but it is your project so take lots of time over it
